Home range
Mapping troop home range
Fit 1–2 individuals per troop, and the seasonal and annual home range emerges as a map. Use it as base data for damage-management and capture planning.
GPS COLLAR FOR JAPANESE MACAQUE
A GPS collar for Japanese macaque, built for municipal operations
Track macaque troops in real time — built for deterrence operations and early warning.
For municipalities and research institutions managing Japanese macaque damage: the LoggLaw G2C monkey model is purpose-built for troop tracking, deterrence-effect evaluation, and early-warning operations.
Built for macaques
Designed for Japanese macaque
A dedicated monkey model sized for Japanese macaque body conformation and behavior. The cotton collar strap degrades naturally and drops off within 2–3 years — no recapture required for retrieval.
No re-capture
Solar × LTE-M
Built-in solar charging minimizes the need to re-capture macaques for battery service. LTE-M sends data directly over the cellular network nationwide.
Deterrence ready
High-frequency mode up to 2-minute fixes
To capture troop movement immediately after deterrence operations, the device can be remotely switched to a high-frequency mode of up to 2-minute GPS fixes and 5-minute uploads.
What is a GPS collar for Japanese macaque?
A GPS collar for Japanese macaque (Macaca fuscata) is a tracking device worn on the neck that logs latitude and longitude via satellite positioning and uploads data over a cellular network. Unlike VHF telemetry, which requires an operator on site to triangulate signals, a GPS collar enables continuous, remote tracking of troop range, movement, and appearance patterns.
Because Japanese macaques live in cohesive troops, fitting one or two individuals in a troop yields a strong estimate of the whole troop's movement. Applications include resident-notification systems, deterrence-effect evaluation, early warning ahead of damage, and analysis of seasonal movement.
This page details the LoggLaw G2C monkey model — its specifications, use cases, and deployments across Japan.
Why GPS collars matter for macaque management
Damage caused by Japanese macaques is hard to address without understanding troop behavior. GPS collars address questions that visual surveys and resident interviews cannot.
See the whole troop's home range
Macaque troops range over several to tens of square kilometers. A GPS collar reveals which settlements, farmland, and forests the troop uses — and when, and how often.
Predict appearances
Accumulated tracking data reveals temporal, seasonal, and spatial appearance patterns. Once a troop is detected approaching a settlement, residents and farmers can be notified early to prevent damage.
Evaluate deterrence effectiveness
Compare troop behavior before and after deterrence operations — fireworks, monkey-dogs, electric fences. The data answers "did it work, how long until they returned, and how did their route change?" with objective evidence.
Distinguish multiple troops
When several troops coexist in a municipality, fitting one collar per troop lets you identify which troop is responsible for which area — and prioritize capture and deterrence accordingly.

Use cases for a Japanese macaque GPS collar
Representative use cases of the LoggLaw G2C monkey model in municipal and research deployments.
Early warning
Early warning of settlement approaches
Register the locations you want to protect — homes, fields, settlement boundaries — on Animal Portal, and a Proximity Alert auto-emails the user when a troop reaches three distance bands (Critical 300m / Warning 600m / Caution 1,000m). No collar-side configuration is required, so the workflow applies instantly to every individual already deployed. (Polygon-area Geofence alerts for entry / exit detection are coming soon.)
Deterrence
Evaluating deterrence effectiveness
Before and after deterrence operations — fireworks, monkey-dogs, electric fences — switch to the high-frequency mode (2-minute GPS fixes / 5-minute uploads) and objectively evaluate troop behavior change: re-intrusion time, route shift, dwell change.
Seasonal movement
Identifying seasonal movement routes
Wintering grounds, summer high-elevation use — annual data reveals seasonal movement routes, supporting prediction and proactive measures ahead of damage periods.
Multi-troop
Distinguishing and managing multiple troops
Fit collars on multiple troops in a municipality to identify each troop's behavior and area. Animal Portal visualizes them simultaneously, helping prioritize response.
Research
Collaboration with universities and research institutions
Macaque troop structure, seasonal behavior, anthropogenic-disturbance responses — used in research collaborations as well. As a Kyoto University-affiliated manufacturer, we support consultations from the study design stage onward.
Macaque GPS collars — by communication design
GPS collars for macaque vary significantly in operational feel depending on the communication scheme. The criteria below matter most for macaque management.
| Criterion (for macaque ops) | Base-station macaque GPS collar | Direct LTE-M macaque GPS collar (LoggLaw G2C) |
|---|---|---|
| Wide-ranging troop tracking | Data gaps outside base-station range | Continuous capture across LTE-M coverage |
| Post-deterrence behavior | Fixed transmission intervals on most models | Remote switch to 2-minute fixes / 5-minute uploads |
| Re-capture burden (power) | Re-capture required at battery end-of-life | Built-in solar minimizes re-capture |
| Operator infrastructure | Local base station, power, maintenance | Cloud only; no field infrastructure |
| Resident notification | Real-time constraints | Real-time sharing and multi-individual management |
| Subsidy (Japan) | Varies by product | Wildlife Damage Prevention Comprehensive Subsidy eligible |
* The comparison above describes general characteristics of the two communication designs and is not exhaustive of any specific vendor's product.

How many collars do I need to track a troop?+
Because Japanese macaques live in cohesive troops, fitting 1–2 individuals per troop is generally sufficient to estimate the troop's home range and movement with good precision. Consider increasing the number for larger troops or troops that may split into subgroups.
How long can the macaque GPS collar operate?+
The LoggLaw G2C monkey model operates approximately one year without any solar input (under 12 GPS fixes/day, 1 data transmission/day). With solar charging, far longer operation is possible. The cotton collar strap is designed to degrade naturally within roughly 2–3 years and drop off the animal.
Can I track troop movement at high frequency right after deterrence?+
Yes. The transmission interval on the LoggLaw G2C is remotely switchable over LTE-M. The default is a few times per day, but around deterrence operations the device can be switched to a high-frequency mode of up to 2-minute GPS fixes and 5-minute uploads — capturing re-intrusion time and route changes in detail.
What animal-welfare considerations apply?+
The monkey model is sized for Japanese macaque body conformation and behavior. The collar-to-body-weight ratio, attachment method, and the naturally degrading cotton strap are all relevant animal-welfare considerations for each deployment. Actual deployment requires the operator to follow local animal-research ethics standards and applicable laws. We can advise on attachment methods — please contact us.
Is the macaque collar subsidy-eligible?+
Yes — eligible under the Japanese Ministry of Agriculture, Forestry and Fisheries' Wildlife Damage Prevention Comprehensive Subsidy. Based on the municipal damage-prevention plan, GPS collar costs for macaque management may be covered.
Can data from the collar drive resident notifications?+
Yes. Animal Portal's Proximity Alert lets you register locations — homes, fields, settlement boundaries — and auto-emails registered users when a troop comes within three distance bands (Critical 300m / Warning 600m / Caution 1,000m). The check runs in the cloud, so no collar-side configuration is needed and it applies to every individual already deployed. A cooldown setting suppresses repeated notifications for the same point / individual. Polygon-area Geofence alerts for entry / exit detection are coming soon.
How does this differ from a base-station-style macaque collar?+
Base-station designs (VHF / 920MHz relay) produce data gaps when the troop is outside the base station's range, and the operator must install and maintain the base station. The LoggLaw G2C transmits directly over LTE-M cellular, so it follows wide-ranging troops and needs no additional field infrastructure.
